HF Presence Detector for Flush Mount

It is a ceiling flush mount active presence detectors integrated Doppler Radar sensor which can respond to the small motion and the light sensor which allows user to set the desired threshold for switching on the light when the ambient light level is below the preset value for more energy savings. The dust, temperature, light, airflow, sound or vibration will not affect the performance of radar sensor and the sensor can penetrate non-metallic materials such as wood board, glass or thin brick wall, etc. to give better detection.


  • High sensitivity for detecting the slightest movement.
  • Sensitivity will not be changed no matter the movement is across or towards to the detector.  
  • Powerful circuit design to control all kinds of lamps and 2 channels for controlling lighting & HVAC.
  • A light detecting sensor is built-in for setting the desired light level to switch on the controlled lighting automatically at the right timing to maximize energy savings and save more of your electricity expense. 
  • Except the provided Lux values, the ambient light level can be read-in by IR as the threshold for switching on / off the loads for more flexible application.
  • An additional function of manually switching on / off the controlled load is feasible by connecting to a pushbutton switch.
  • IR remote control is available for easy and quick settings (note: IR remote control is for optional purchase).
